Blueberries do not lend themselves to dehydration. That said, the folks at Augason Farms did an excellent job of it. Ingredients: freeze dried blueberries. That's it. No artificial anything. I won't recommend them for 'dry snacking', but they are very tasty once they've been rehydrated. They make a very good addition to AF's granola and would probably be good in muffins or pancakes.
